Symptoms Of a Bad ABS Module

You have the security and safety you require when driving with an ABS control module that is functioning properly. If this component starts to malfunction, you become more likely to get in an accident, especially if you need to stop quickly.  In order to keep you from losing control of the vehicle while braking forcefully, the ABS control module limits the brake pressure to the caliper and restricts the wheel speeds.

An ABS warning light on your dashboard is the most typical sign of a failing ABS control module. Wheels locking up while braking on slick surfaces is another possibility. A stiff or sluggish brake pedal is an additional, less frequent indicator.

Well, in this Article I’ll be discussing the symptoms of a bad ABS module.


What are the symptoms of a bad ABS module?

Locking Wheels

When traction is lost, the ABS control module prevents the wheels from locking up. The information required to prevent the wheels from locking, however, is inaccurate because this component fails. The ABS control module may be responsible if your wheels start to lock up when traction is lost. Usually, you won’t notice the issue unless you use the brakes suddenly. Otherwise, a locked brake caliper may be responsible if the wheel locks up repeatedly.

ABS Warning Light

All more recent vehicles are equipped with an ABS dashboard light to alert you of any issues. One cause for the light to come on is a malfunctioning ABS control module. The ABS symbol is illuminated in amber on more recent models. Older models, however, lack this specific light. Instead, they might use the Check Engine Light.  When the ABS light comes on, the system may completely stop working. You shouldn’t drive without the ABS, even if you can. It is an essential safety measure designed to safeguard you.

Increased Braking Effort

The brake pedal should still stop you when you depress it. The effort required to stop, though, might become more obvious.  You can find that as time goes on, applying the brakes to stop your car and depressing the pedal requires more effort. Have the system checked if it seems like your legs are getting a workout every time you need to stop.

Speedometer Failure

There are a few uncommon situations where the speedometer is impacted by an ABS control module failure. Either the wrong speed will be displayed, or 0 mph will be the needle’s resting position. The check engine light or brake light may then turn on. Even if those indicators don’t illuminate, a malfunctioning speedometer is a valid reason to get your car inspected. In essence, seek immediate assistance from a repair if you suspect that your ABS control module may be malfunctioning.  Or, even better, have one come to you.

Unresponsive Brake Pedal

You want to be sure that the car will stop when you press the brake pedal. However, a defective ABS control module can make stopping more challenging. You could initially notice the heightened braking effort mentioned above. This effort will intensify over time and could eventually destroy your ability to operate the brake pedal totally.  Make sure to do a thorough system inspection since low brake fluid levels can possibly be the root of this problem. To make sure there is no air in the lines, you may want to think about having the brake fluid system cleansed.


When the ABS module is defective, it may result in the loss of anti-lock braking, turn on the ABS warning light, cause unpredictable brake behavior, lessen the effectiveness of the traction control system, produce diagnostic trouble codes, and produce odd noises coming from the ABS pump or motor, all of which may have an impact on the safety and performance of the vehicle.
